Definition that contains radiant energy
- flash a sudden intense burst of radiant energy
- transmission the fraction of radiant energy that passes through a substance
- opaque not transmitting or reflecting light or radiant energy; impenetrable to sight
- radiometer meter to detect and measure radiant energy (electromagnetic or acoustic)
- photosynthesis synthesis of compounds with the aid of radiant energy (especially in plants)
- reflectance the fraction of radiant energy that is reflected from a surface
- reflectivity the fraction of radiant energy that is reflected from a surface
- photovoltaic producing a voltage when exposed to radiant energy (especially light)
- absorption coefficient a measure of the rate of decrease in the intensity of electromagnetic radiation (as light) as it passes through a given substance; the fraction of incident radiant energy absorbed per unit mass or thickness of an absorber
- photochemical exchange an exchange produced by the chemical action of radiant energy (especially light)
